摘　　要：This paper presents a comprehensive analysis of the MD-BFKL equation,considering both shadowing and anti-shadowing effects in gluon recombination processes.By deriving analytical expressions for unintegrated gluon distributions through the solution of the MD-BFKL equation,with and without the incorporation of the antishadowing effect,we offer new insights into the influence of these effects on the behavior of unintegrated gluon distributions.Our results,when compared to those from the CT18NLO gluon distribution function,demonstrate that the anti-shadowing effect has a notably stronger impact on the characteristics of unintegrated gluon distributions,particularly in regions of high rapidity and momentum.This work significantly contributes to the understanding of gluon recombination mechanisms and their implications in high energy physics.
